Description and Introduction

Adjustable Precision Shunt Regulator 3-SOT-89 0 to 70 The TL432CPK is a precision programmable shunt regulator manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Reference Voltage:** 1.24V (typical)  
- **Operating Cathode Current Range:** 1mA to 100mA  
- **Cathode Voltage Range:** Up to 36V  
- **Temperature Stability:** ±0.4% (typical) over full temperature range  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOT-23 (3-Pin)  
- **Accuracy:** ±1% (typical)  

### **Descriptions:**  
- The TL432CPK is a low-voltage adjustable shunt regulator with a tight reference voltage tolerance.  
- It is designed to replace the TL431 in applications requiring lower voltage operation.  
- The device is commonly used in switching power supplies, battery chargers, and precision voltage references.  
- It features a programmable output voltage via two external resistors.  

### **Features:**  
- **Adjustable Output Voltage:** Set via external resistors (from 1.24V up to 36V).  
- **Low Dynamic Output Impedance:** 0.2Ω (typical).  
- **Low Operating Current:** 80µA (typical).  
- **Wide Operating Cathode Current Range:** 1mA to 100mA.  
- **Improved Stability with Capacitive Loads:** Compared to the TL431.  
- **Available in Small SOT-23 Package:** Suitable for space-constrained applications.  

This information is based on the manufacturer's datasheet and technical documentation.
